Seoul’s benchmark Kospi index achieved a historic milestone on Wednesday, opening above 7,000 for the very first time. This significant surge in the South Korean stock market was fueled by growing optimism that Middle East tensions may be easing, which propelled a sharp rally across local markets.
The benchmark index commenced trading at 7,093.01, marking a robust 2.25 percent increase from its previous close, and quickly extended its gains in the initial minutes of the session. It soared to an intraday high of 7,311.54, stabilizing near the 7,280 mark by 9:15 a.m.
This explosive upward movement triggered a crucial buy-side sidecar within approximately six minutes of the session’s start. This circuit breaker, activated after Kospi 200 futures surged by more than 5 percent, temporarily halted program sell orders for five minutes. It marked the eighth such buy-side sidecar event recorded this year.
Contributing to the market’s strength, South Korea’s two largest chipmakers also recorded unprecedented highs. Samsung Electronics surpassed 250,000 won, while SK Hynix broke the 1.6 million won threshold for the first time ever.
Wednesday’s remarkable rally on the Kospi mirrored a strong rebound observed in New York markets. On Tuesday, easing global oil prices and renewed hopes for a de-escalation of Middle East tensions revitalized investor risk appetite. The S&P 500 advanced 0.8 percent, and the Nasdaq Composite climbed 1 percent to reach fresh records, while the Dow Jones Industrial Average also posted a gain of 0.7 percent.
The Kospi’s monumental leap past the 7,000 mark follows its recent achievements, crossing 6,000 on Feb. 25 and 5,000 on Jan. 22. From its closing level of 4,214 at the end of 2025, the index has experienced an impressive climb of approximately 68 percent at Wednesday’s opening, exceeding a 70 percent rise at its early intraday peak.
